Last year, I really enjoyed carving turns with my twin tip, and was expecting that the experience would be even better on a surfboard.
What a DISAPPOINTMENT.
It appears to me that the placement of fins at the back of the board is ill-suited to a sport in which the rider is pulled and must provide resistance to the pull.
It seems to me that the fin(s) should be under the inside of the heel of the lead foot (directional board) or between the feet (twin tip).
The twin tip configuration could use three fins in a triangle pattern with two fins for strong heel-side edging and one fin for toe-side carving.
I am going to assess these designs by 1. Moving the fin box of an old directional surfboard from the back to under the front foot straps; and 2. Connecting the front end of two surfboards to make a twin tip in the shape of a banana.
I would love to hear your thoughts on this idea, and would greatly appreciate any advice for connecting the two boards and mounting the fin boxes.
